The present work carried out in 2008 aimed at studying the effects of a polyherbal supplement on cross bred does, starting from the last month of pregnancy to weaning, on milk yield, kid birth weight and growth rate. Thirty does were divided into three groups (treatments) of ten does in each pen. These three treatments were given to the three groups respectively; low level supplementation (LS), high level supplementation (HS) and non-supplemented treatment (NS) as control. The low supplemented goats were given 125 mg/kg body weight per day polyherbal combination and the high supplemented goats were given 250 mg/kg body weight per day.
Fifty-nine kids were born from all the experimental animals. There was no difference on milk yield between the supplemented groups and control (P>0.05), although polyherbal supplementation had positive effect on litter birth weight and growth rate compared to control. Weaning weights were higher (P<0.001) in LS and HS compare to NS does. In both supplemented treatments compared to control, mortalities and morbidities were also lower in kids born. It was concluded that pre-partum to weaning supplementation increased kids growth rates and weaning weights, and reduced kid mortalities, but it did not have a significant effect on milk production.
